I had my first ultrasound yesterday and according to my LMP, I am about 8 weeks along. The dr. saw everything as it should be...yolk sac, fetal pole, my enlarged uterus, etc. But, she did not detect a heartbeat. She said the baby's measurements appear to be around 6-7 weeks and that it could mean that I'm still a little early to see the heartbeat. I totally don't understand the weeks and how they are calculated. If I'm 8 weeks preg, why is the baby 2 weeks behind? Can someone explain this? She also said to "be guarded and prepared" if this is a non-viable pregnancy, meaning miscarriage obviously.
I am so horrified at the thought of this. I have been totally okay- no spotting or bleeding, cramping, etc. and have had all the normal preg symptoms up to now. Can anyone tell me from your experience if this has happened to you? Should I be worried that she didn't see a heartbeat yet? She told me to come back in 4-5 days to the perinatal center where they have the super high-tech ultrasound machines for another one. She said that if they don't detect the heartbeat that I have miscarried.
I AM SO SCARED AND UPSET. help!
